| Abstract(in English) | This paper presents a meeting diarization system that estimates who spoke when in a meeting. Our proposed system is realized by using a noise robust voice activity detector (VAD), a direction of arrival (DOA) estimator, and a DOA classifier. This paper proposes two methods for improving diarization performance. As the first proposal, we employ a DOA at each time-frequency slot (TFDOA) so that multiple DOAs can be estimated at a frame when multiple speakers speak simultaneously. The second proposal is to integrate VAD and DOA in a probabilistic way. This paper reports how such proposals improve diarization performance for real meetings/conversations. |
